We know that every bike ride taken is a positive - it contributes to safety-in-numbers, it hopefully gets counted somehow to justify more facilities, it is cleaner and healthier than alternatives, it helps normalize the behavior, etc etc.
But here's a theory - i think every bike ride can bring happiness to other riders. Validates us, lets us know that we're not alone, gives us hope that all the fights are leading us to a marginally-better future.
So go take a ride, because it makes me happy.
